Autumn: According to our model results, the mean autumn temperature in the Swedish reindeer grazing areas will increase by 3°C within the next 20 years. Especially in the south in November, the maximum temperatures during the days will regularly get close to 0°C and raise the risk for thawing and refreezing events and resulting ice crust on the snow. The snow season will start later and the amount of rain- and snowfall will also change: October will become wetter while November will become up to 25% dryer compared with the period 1979-2000.
